ToV milzlwhom it may; concern.-

Be it known that I, Lotos SCHUTTE, n citizen of the United States of Ann-rica, rcsiding in the cit and countyr oF Phiiadeiphia, in the State of igen'nsyivunla, have invented a certain new and useful Im rovemcnt in Eductor-Condensers, of which the foilovzin` is a truc and exact description, rofcrencc iheine; had to the accomfpanying drawings, which form c part therco Thin` invention rciatce to the einen of condonsers in which steam is eonde'nncd hy heing brought into contact with a moving jot of watcr, such oondenscrs consisting, cssoutiaily, in a suitablccasing in which is situated n combining-tube provided with lntcral pcrforations for the entrance of the strani and connecting at bottom with n, dischnrgwtnhc, the casing boing also provided with a watir jet nozzle leading into the end of thc combinmgdsube and ali such condcnsors hcvin,lr at the dciivery end of the ,tuhe what is known ns the throat, said throat being thc portion ol the tube marie l of the combining :md discharge tubes inwhich thc jct .attains its highest speed.

Tho ohject'of this invention is to increase thc eificicney of Such condcnsers hy removinnJ l;condensed water, "or thc largos-t par@ thereof, from thefichaust-stcmn enteringthcY Condenser bciorcfsuch steam enters the cornhiningfjiewthcrehv materially increasing the driving 'action of the Steam and proline, ing, .incidentally a higher vacuum than would he the case if this condcnscd water was pcrinittedto cntcr the combining-tribe tocther with the steam, and I aooonizfhsh Ythier y providing a collecting-chamba for the water and connecting auch chamimrV with a .water-inict whichl form in the throat of the condenser, in which throat hy reason of the high speod'of the jet there is c tendency to produce a highor vacuum than oxist-e in any part of the casing. In the sccond piace l increase the officieux-, y of thc condensor h y ma king the water-inlet in the throat of anonim- Vlar or suhstontiiiliy annoia: form, so that the rvatcr cntcring thc throat forros, in client, an annular iluid-thront, which is henoiiciiii hoth as diminishing thc friction which the jot encounters at this point end lsoi Yn'iionling); n moans whereby a ccrtcin rcgoiation of the diameter of the cficctivc'throat can ho oil'cctcd, and in ccrtnin casos l. hnve found it mivisnhlc to provided Wator-conduit loading to the inlot in the throatindependent oi' tho condi-.immiwhich my invfntion is illustratori, land in Figure 1 is n contrai vcrticni Sanction through a condenser provided with my iniroveinents; Fig. 2, a cross-section ofi the inc 2 2 of Fif; V1 Fin. 3 n sectioned cievation h I h l c of a modiiicdform of condenser, also provided with my improvements; Fig. 4, im cicvn-tion of :i condm\si\r,si|owing another modification adopted for usc in conncction with my imprrwvmcnts; Fi 5, a scctional cicvn Vtion showing stili another modification in the Inode of ntiiizing my invention; Fi f. 6, an eniargcd ecctionni elevation of the t ront and parts innncdiatcly connected therewith, as shown in Fig. 3, the water-jet being conventionniiy indicated in this view; and Fig. 7 is a sixninr scctionci elevation of the throat and ports Yiininedintcly connected therewith in thc construction shown in Fig. 5.

Q, which iit into the slots B, as,

. regulating and cut-oil' valve D', Fig. 3, is a izafiie-plate placed directly in front of the stcamadlnission port and actin to prevent any direct llow of the water wit the steam to thc condensing-tube.

I indicates the discharge-tube of the condenser, and E indicates the ortions of the combining-tube which is nown as the throat, the dotted lines X X indicating substantial] the effective length of this throat ortlon of the condenser.

E', lfirs. 1, 5, and 7,indicates an annular water-inlet formed in the throat and connccted with what Iwillcall a supplemental or Lsecond collecting-chamber, (indicated at E2.)

In the modification shown in Figs. 3 and 6 what is, in cil'cct, an annular water-inlet is provided in the throat by the revision of the annularly-dis osed system o conduits, (indicated at e,i)said 'conduits leading directl from the bottom of the chamber A throug the throat E of the condenser, as shown, and being in the special modification'illustrated formed in two annular series, one situated above the other.

In the construction indicated in Fi l the chamber A is connected with the c amber E2 by the conduit F', leading from the chamber A to a port F, which m turn connects with the chamber E. In this special construction a non-return check-valve F is provided, and a further ort Fa is connected with a conduit F, throu which an independent sup ly of water canhe furnished tothe chamber LF and the inlet E', the valve F closing whenever the pressure 'of the inde endent supply of water at the point where t e valve is situated exceeds the pressure in the casing. Practically the same arrangement is shown in Fig. 4 the collecting-chamber.a2 being connected by a pipe f' with the miem the throat, a non-return valve j" being provided and an independent supplypipef being also` provided. J

In the construction shown in Fig. 3 the anfrling perforationse lead directly rom the coilectinfchamber A to the throat; but I have indicated an indepenident supply-pi e H, which lin this constructfon leads into the chamber A.

In the construction showh in Fig'. 5 the annular chamber E is connected with the chamber A' by vertical perforations or passages F, and in this construction an independent suppl of water is provided for through the pipe which, as s iown, is rovided with `a the construction of Fig. 1 a cup-like baffle I) isformed as a prolon ation of a seatcasting J, which supports t e lower end of the combining-tube, and is formed with a lip J', which forlns the upper edge of the inlet loadingl to. the throat.

In I* Lg. the @wer end ef the combining; tube is supported directly on the .upper end of the casting or section in which the delivery-tube is formed, and in Fig. 5 the seatcasting, here indicated at is not dissimilar to the seat-castin J of Izig. 1, but is here shown as providet with lateral recesses, (indicated at ji which receive outwardly-extending lugs C4 of the combinin -tube and act to prevent rotation of said tube.

In operation it will be seen that the condensed water in the steam will for the most part collect in the chamber or chambers provided for its rece tion-that is, the chamber Aor the chamler aL-and will ass from said chamber or chambers throug the conduits described to the annular on substantially annular water-inlet rovided in the throat E, the eflicienc of t e condenser being thereby promote both because of the greater dryness of the steam entering the combining-tube and because of the diminution of friction in the throat of the condenser, this last function bein further promoted by the inde endent su p y of water to the inlet in the t oat by t e means indicated and above described.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

`1. In an eduction-condenser having a casing, a condenser-tube situated therein and in communication therewith through perforations, awater-jet nozzle directed into the end of the condenser-tube and a throat situated at the delivery end oi the tube and wherein the jet attains its maximum s eed, the combination therewith, of a chamber adapted to collect condensed water in the steam passing to the` condenser, an annular or substantially annular water-inlet enterin the throat of the condenser, a connection om the waterchamber to said inlet, and an independent water-supply conduit also connecting to said inlet in t e throat.

" 2, In an eduction-condenser having a casing,-a condenser-tube situated therein and in communication therewith thro tions, a water-j et nozzle directed into the end of the condenser-tube and a throat situated at the delivery end oi the tube and wherein the jet attains its maximum speed, the combination therewith of a baiile'arrangd in the path of the steam entering the casing,y s. water-collecting chamber, an inlet enterin the throat, and a conduit from the water-co ecting chamber to said inlet.
